Here's the first puzzle, a warm-up.
This is a recent heat map of memory usage in an HTTP service. What caused these four prominent "spurs" you see along the top?
(More context, not all necessarily relevant: The service is running in Kubernetes, so the samples represent containers, each container running multiple workers. The Y axis, not shown, starts at zero. Time zone for X axis is unspecified.)
Anything else can you figure out from this graph?
